Starting Dahlia Plants in Containers

In this post, I will share a few videos, images and details on how to start Dahlia plants in containers.  This process is one I’ve been using since 2010 successfully.


Starting Dahlia Plants in Containers

In the video below I share what is going on in my greenhouse and how I will be starting the Dahlias in this space.  If you don’t have a greenhouse you can still start the tubers early.  In the past I had the containers on a wagon that could be pulled into the garage or greenhouse to avoid frost in April.  If you are in warmer hardiness zones you won’t have to worry about this.

More Details About Planting Dahlia Plants From Tubers

In this short video, I share close up details on how to get started with tubers.  It is so much fun planting these ahead of time in my hardiness zone. I wouldn’t start this in the ground until 2 weeks before the last frost.  Giving the plant a head start in a container that can be moved around has been successful for me.  Check out the video below featuring how the tubers are planted in containers each year.

  • A clean container with drainage hole is a must for growing dahlias.

  • Do not let the planting go completely dry for over 2 days.
  • Keep the soil fairly damp but not too wet!
  • Have fun and grow many varieties to find the one you love.
